To detect prognostic factors for successful sialoendoscopic removal of salivary stones.
Retrospective case series.
Tertiary referral hospital.
Forty-nine consecutive patients who underwent sialoendoscopy for sialolithiasis between January 1, 2008, and January 1, 2010, at University Hospital of Cologne, Cologne, Germany.
Diagnostic and interventional sialoendoscopy using local anesthesia.
Stone removal rate, size, mobility, shape, and location, as well as clinical follow-up data.
Sixty-one percent (39 of 64) of all salivary stones were removed endoscopically. The cutoff point for endoscopic removal was between 5 and 6 mm in stone diameter. Small size, good mobility, round or oval, and distal location of a salivary stone were positive prognostic factors for sialoendoscopic removal, with sialolith mobility having the greatest effect in multivariate analysis.
Small size, good mobility, round or oval, and distal location of a salivary stone in the main duct predict significantly greater probability of endoscopic removal and consequently are positive prognostic factors.
检测涎腺内镜成功取出涎石的预后因素。
回顾性病例系列研究。
三级转诊医院。
2008年1月1日至2010年1月1日期间在德国科隆大学医院因涎石病接受涎腺内镜检查的49例连续患者。
采用局部麻醉进行诊断性和介入性涎腺内镜检查。
结石取出率、大小、活动度、形状和位置，以及临床随访数据。
所有涎石中有61%（64颗中的39颗）通过内镜取出。内镜取出的结石直径临界值在5至6毫米之间。涎石体积小、活动度好、呈圆形或椭圆形以及位于导管远端是涎腺内镜取出的阳性预后因素，其中涎石活动度在多因素分析中影响最大。
主导管内涎石体积小、活动度好、呈圆形或椭圆形以及位于远端预示着内镜取出的可能性显著更高，因此是阳性预后因素。
